if you have no history for the car try to change oils and filters.
install a transparent hose between fuel filter and engine and see if you get air. fuel tank pipes can get corroded .
fuel gauge has a small mechanical device that lowers the voltage from 12 to ~7 for the temperature meter. that gets temperature spikes sometimes (normally both fuel and temp hike up)and its not a nice sight to see the temp needle going into red zone.
then….check radiator (mine went to a specialist shop, they recore it after they said it had poor efficiency), check fan clutch, which might have silicone oil missing inside and check thermostat.
ultimately, drive it carefully and have fun!
ps oh God, do change those tires ! had the same ones , one nearly exploded on the highway in France.they are stiff rubber by now and just awful, they are a genuine danger.
